I've been a customer for 4 years. JiffyShirts is reliable, communicative and either competitively priced or better priced than other companies. Since I wear so many hats as the sole employee of my company, everything falls on my shoulders. After I place my order for what I need I don't have to think about it again. JS takes off some of the work load with its reliability.
Customer service is something I pride myself in as a small business owner. The folx at JS are very communicative when I have contacted them with an issue or question. They also have been quick to let me know if something I ordered ran out right before I paid so I can then communicate with MY customers and set expectations.
